8 Claims.

The primary object of our invention is to devise a novel mechanism toaccurately measure the depth of filler in a chamber in which it is beingassembled in small quantities to build up a complete bunch charge.

Each small quantity is pressed to the bottom of the sizing chamberbefore the next small quantity is fed into the sizing chamber. Thiscauses the bunch charges to have a constant density, so that the buncheswill be of uniform size and density.

The bottom of the sizing chamber has a closure which is held in apositively closed position during the operation of building up a bunchcharge. To obtain these results, novel mechanism is employed to controlunder spring pressure the si A driven belt 2 drives a pu y 3 to drive aShaft ing operations. l which is connected by a clutch 5 with a shaft Assoon as the bunch charge is built upto the 6 to drive the latter.

A stop lever Fi u e 1 i a p pl i ofvmeph nism for r .3 sloos lm n d o the rock sh ft i3 and has an arm 39 contacting with the lever IEto move the lever 38 away from a lever 40, the lever 40 being moved inthe opposite direction by a spring 53. The lever 40 is pivotallysupported at its upper end and is connected by a link 4| with a threearmed lever 42, pivoted at 43 and having one arm connected by a link 44with a lever 45 fulcrumed at 45 on an arm 49.- The lever 45 has a roller41, cooperating with a cam 48 on the shaft 1.

A clutch lever 49 pivoted at 50 has a clutch arm 5| controllingengagement of the discs of the clutch 5.

The tobacco, either long or short filler, is intermittently fed in smallquantities, in any desired manner, on a plate 52 from which each smallquantity is removed by a pusher to the sizing or measuring chamber, in asimilar manner to that shown in our copending application, Serial No.372,058, or in any other desired manner.

The lever 38 is retained in raised position by a spring 54 which tendsto rock the lever 38 upwardly against a stop 55.

The tobacco is fed in smallquantities in any desired manner to the plate52, and is intermittently fed from the plate to the sizing box in thefollowing manner. The shaft 1 has a crank 56 fixed to it, and connectedby a link 51 to a lever 58, pivotally supported at 59, and connected toa link 60, which is connected with a pusher BI. When the shaft 7 is notbeing driven, the tobacco is not fed from the plate 52 to the sizingbox.

The operation will now be apparent to those skilled in this art and isas follows:

The tobacco, in the form of either long or short filler, isintermittently fed in small quantities less than a bunch charge from theplate 52 to the sizing box 2i. During this operation the worm shaft 6and shaft 1 are revolving and the rock shaft I I is being rocked. Aftereach small quantity of tobacco is fed to the sizing box, the sizingplunger i5 is rocked downwardly pressing such small quantity to thelower part of the sizing box against the closure formed by the lever 22.This pressing operation is repeated for each small quantity until thebunch charge is built up to a predetermined height for a single bunchcharge. When this point is reached, the sizing plunger I 5 fixed to theshaft l I, as is the lever I4, will be arrested at an earlier point inits movement than when moving to press the proceeding small tobaccoquantities, while the lever I0 will continue its stroke through crank 3,link 9. The set screw IE will contact the lever l8, bearing against thearm 39 to rock it out of the path of the lever 49, thereby permittingthe roller 4! to move into the path of the cam 48, thus rocking thelever 49 to effect the release of the clutch 5, and thereby stopping thefeed of tobacco filler.

In order to provide for the release of the hook 25 from the bottomclosure 22 of the sizing box, the hook 25 on the lever 2'! is moveddownwardly with such lever to release the arm 25. The lever 21 isoperated through link 3|, lever 32 and cam 33.

The shaft 35 makes one revolution during the cycle of the machine. Theshaft 4 is continuously revolved and is driven at a faster rate than theshaft 35.

The bunch charge is moved out of the sizing box by an ejecting plunger,similar to that shown in our Patent Number 2,243,699 of May 27, 1941, tobe received in the pocket of a rolling apron for the application of abinder in a conventional manner. The ejecting plunger moves downward- 1yas described in our Patent No. 2,243,699, causing the bottom closure ofthe sizing box to be moved into its open position. The machine completesone cycle and the tobacco feed stops. The machine is started by pushingthe lever 40 rearwardly, thereby rocking the lever 42 to move the link44 downwardly, and cause the lever 5| to cause. engagement of the clutch5. When the link 44 moves downwarly, the lever 45 is rocked downwardly,moving roller 41 out of the path of the cam 48, thereby allowing lever49 to move. The clutch 5 is released when the roller 41 is in the pathof the cam- 48.

It now will be apparent that the sizing plunger is actuated by ayielding driving connection to measure the height of a bunch charge, andwhen the bunch charge has been built up to the required height, means isactuated by the yielding driving connection to stop the feed of tobaccoto the sizing box.
